Lecture
This lecture covers the transition from atomic orbitals to molecular orbitals, explaining the Hamiltonian operator that describes the total energy of quantum systems. It delves into the Schrödinger equation, approximations to solve it, quantum numbers, electronic configurations, and valence electrons. The lecture also explores the VSEPR model, valence bond theory, hybridization, and the molecular orbital theory for covalent bonds. It discusses the formation of single and multiple carbon-carbon bonds, molecular orbital energy diagrams, and the complementarity of valence bond and molecular orbital theories. The presentation concludes with a detailed explanation of the molecular orbital view of double and triple carbon-carbon bonds, including rotational symmetry and energy diagrams.
